Helium does NOT require root. All Android users can use Helium to backup and sync Android applications.
Helium lets you backup your apps and data to your SD card or cloud storage. With Helium, you can sync app data from your other Android devices– even if they are not on the same network. Set up backup schedules with Helium, and never lose data again.

Note: Helium is NOT available to Motorola devices. This is because Motorola phones have a bug that break Android’s backup mechanism. Until this is fixed by Motorola, Helium will not work on those Androids. You can download Helium manually here:

If you find that Helium *does* work on your Motorola Android, please notify me.

Note: Some Sony devices have issues with Helium. This includes the Xperia S and Xperia Z. Sony has *disabled* backup on these devices completely.
